-LRB- CNN -RRB- A grand jury in Clark County , Nevada , has indicted a 19-year-old man accused of fatally shooting his neighbor in front of her house last month .

Erich Nowsch Jr. faces charges of murder with a deadly weapon , attempted murder and firing a gun from within a car .

Police say Nowsch shot Tammy Meyers , 44 , in front of her home after the car he was riding in followed her home February 12 .

Nowsch 's attorney , Conrad Claus , has said his client will argue self-defense .

The Meyers family told police that Tammy Meyers was giving her daughter a driving lesson when there was a confrontation with the driver of another car . Tammy Meyers drove home and sent her inside to get her brother , Brandon , who allegedly brought a 9mm handgun . Tammy Meyers and her son then went back out , police said .

They encountered the other car again , and there was gunfire , police said . Investigators found casings from six .45 - caliber rounds at that scene .

Nowsch 's lawyer said after his client 's first court appearance that Brandon Meyers pointed a gun before anyone started shooting . He said the family 's story about a road-rage incident and what reportedly followed do n't add up .

After zipping away from the first shooting , Tammy Meyers drove home and the other car , a silver Audi , went there also . Police said Nowsch shot at both Tammy and Brandon Meyers . Tammy Meyers was hit in the head and died two days later at a hospital . Brandon Meyers , who police said returned fire at the home , was not injured .

The driver of the silver Audi has yet to be found by authorities . That suspect was n't named in Thursday 's indictment .

Nowsch was arrested five days after the killing in his family 's house , just one block away from the Meyers ' home . He is due in court Tuesday for a preliminary hearing .
